ThingSpeak can be used to easily monitor CPU usage %, memory usage %, and disk usage % on any Linux machine connected to the internet.
First, create a new Channel, and fill out the field names as follows: Field 1 = “CPU Usage (%)”, Field2 = “Memory Usage (%)”, Field 3 =… read more >>

Once your data gets into ThingSpeak, you than want to do something with it. A first step is to see the data. If the data are sensor values from a Nest thermostat for example, then you want to see it as a chart. We added a new way to visualize… read more >>

[Marcus Olsson] of slickstreamer made a battery-powered temperature logger using ThingSpeak to store and visualize the data collected. He chose the Electric Imp Wi-Fi module for connectivity. The project is complete with a 3D printed case.

All of the source code to connect Electric Imp to ThingSpeak and the 3D printer design… read more >>

[Risto] from Supermechanical wrote a tutorial on how to use the Twine with ThingSpeak web services such as Data Logging and Charting. The tutorial explains how you can use the Twine’s easy-to-use sensor module to trigger events and push data over to ThingSpeak. This opens up the data captured by Twine and allows… read more >>

ThingSpeak user, “SolarInKrimpen”, from Rotterdam, Netherlands, created a solar power monitoring system that reports data collected by solar panels and feeds the data to web services such as ThingSpeak, Cosm, and PVoutput. They are collecting data such as, AC Wattage collected by a Pulse Counter, Total KWH per day, temperature of… read more >>

Via Twitter, we caught wind of a project by a group of Rutgers University SCI ITI students. As their final project, the team built a working model of a smart home using sensors connected to ThingSpeak cloud services via Arduino and chipKit. They were able to embed their data and integrate with their Drupal-based website and show… read more >>

We have recently received a few email about accessing historical data. We even noticed some posts on other forums asking about older data.
All ThingSpeak Channels are continuous logs of data. Using API commands, you can access recent data and historical data. The default API parameters allow for easy access to recent data. To get… read more >>

[david] from Toute la Domotique adapted the Teracom box to connect to ThingSpeak web services for data logging of sensors. In his article, “Suivi de Température“, David covers the ThingSpeak integration in a 6 part tutorial written in French.

The Teracom box allows for 1-wire connections to sensors. David connected a… read more >>

[lars] created a weather station from scratch using sensors and bits from SparkFun and Adafruit. Lars wanted to log weather data and access it from remotely. He built the weather station using humidity, temperature, pressure, and light sensors collecting data from his apartment in Ithaca, NY. Originally, Lars was collecting data with his own web… read more >>

HomeVisionXL adds a ThingSpeak Plugin for environmental data logging to their home automation controller. HomeVisionXL “is a cross-platform tool for developing schedules for the HomeVision integrated home controller.” The plugin was created by ThingSpeak user [bgardner] and adds data logging capability to the HomeVision home automation system.
